Question

So is the `Prefect Agent` responsible for passing output of one task as input of another task in Prefect flow DAG since the Prefect server manages no code or input output data i m trying to wrap my heads around what is the responsibility of the Agent Maybe an architecture diagram might help

Hi < BK Lau> the agent is purely responsible for creating the process that runs the flow The flow and task runners handle passing data

< Zanie> Is the flow task runners also responsible for pulling code dependencies artifacts configs it needs into the execution environment

Zanie · Answer

The process looks a bit like this Write your flow Register your flow Flow storage is built flow code is written somewhere in your infrastructure Flow metadata is serialized sent to Prefect Run an agent queries Prefect for flows to run Run your flow from the UI marks the flow as ready to run Agent detects flow gets metadata from Prefect Agent locates flow storage in your infra Creates a process to execute the flow

That s dependent on the type of run configuration you re using If you re using a `DockerAgent` `DockerRun` then you just put all of that in a docker image and the agent creates a container with that image that executes your flow

Zanie · Answer

If you re using a `LocalAgent` then whatever environment your agent is in is the environment your code runs in roughly
